I discussed doing a stereo prewire for my 5.0 TA with Sarah at ETI. She said "We only have 16 gauge wire available at our facility. We can run this wire to all of the locations you have requested for $100. If you wish to send us 14 gauge ribbon wire, we can run it for $75. The speaker prewire charge of $75 also includes the 12V drop for Stereo power." ETI provides the wire for the 12V drop which they earlier told me is 14 gauge. FYI, the "ribbon wire" that Sarah mention is just two conduct wire commonly used for speakers.
Here are my requirements for the $75 stereo prewire in a 5.0 TA:
- 4 speakers in the normal locations (2 in the dinette, 2 in the bedroom)
- Stereo unit in the normal location (under the cabinet by the exterior door)
- 2 pairs of wires from the stereo to under the passenger dinette bench for a sub-woofer
- 100 ft of 14 gauge wire provided by me
So, if your requirements are different, the $75 fee might be different.
It is interesting that Sarah said they have 16 gauge wire available for the prewire, however Ian G mentioned earlier that he saw much smaller speaker wire in his factory installed stereo system. Perhaps you get bigger wire when you are only doing a stereo prewire. I didn't follow-up on this to get clarification.
I sent this 14 gauge speaker wire to ETI: http://a.co/bZiZP5W
In the future I will decide what stereo components I want to use and install them myself. It is worth $103 CDN (ETI labor + wire) for me to have ETI install the wire.
This discussion of wire gauge with Sarah brought up something I wasn't aware of regarding trailer wiring. I was confused why they had 14 gauge wire for 12V prewire drops, but not for speakers. They use one conductor wire for the 12V circuits (positive), and two conductor wire for the speakers. The negative 12V connection goes to the trailer frame. That reminds me to put on my future trailer improvements list to tie all the 12V wiring grounds together under the trailer (I've seen this previously mentioned).
